Fpga implementation on advance traffic light
- 1. FPGA Implementation on Advance Traffic Light Control System Presented By V.MANASA (17A11D8109)
- 2. AIM: •In this project, we are designing an Intelligent Transport System (ITS) application for Traffic Light Controller (TLC) by using Field Programmable Gate Array (FPGA). •The integration of FPGA and all the small devices will be integrated by using Very Large Scale Integration (VLSI). •The code is written in Verilog HDL design pattern and synthesis is done in XILINX of version 14.2.
- 3. • A design of a modern Traffic Light Control (TLC) System to manage the road traffic. • The approach is by controlling the access to areas shared among multiple intersections and allocating effective time between various users, during peak and off-peak hours. INTRODUCTION:
- 4. • Intelligent Transportation Systems (ITS) applications for traffic signals – including communications systems, adaptive control systems, traffic responsive, real-time data collection and analysis, and maintenance management systems. • The heart of the system is a Finite State Machine (FSM) that directs the unit to light the main and side street lights at appropriate times for the specified time intervals.
- 5. 1. Safe and efficient traffic light flow 2. Assign right of way to maximize capacity, minimize and reduce collision and conflict
- 6. SOFTWARE USED: XILINX 14.5 LANGUAGE USED: Verilog HDL
- 8. In this road structure, there are six traffics, represented by T1, T2, T3, T4, T5 and T6 to be controlled. T1 and T2 have been identified as the main road for the first junction while T4 and T6 are for the second junction. The last two traffic lights, T3 and T5 are the smaller roads. Control method for the TLC during peak hour.
- 9. It is often useful to be able to sequence through an arbitrary number of states , staying in each state an arbitrary amount of time. Consider the set of traffic lights shown in Figure.
- 10. The lights are assumed to be at afour- way intersection with one street going north-south and the other road going east-west.
- 11. A state diagram for controlling these traffic lights is shown in Fig.
- 12. ADVANTAGES: 1. Low power consumption. 2. Easy to implement. 3. Speed of operation.
- 13. APPLICATIONS: •to control the traffic signals at any junction. •real time vechile management systems •in parking systems
- 14. CONCLUSION: The modern ways of multi-way traffic management improves the traffic condition up to a large extent. Advanced signaling controllers contribute to the improvement of the urban traffic; which is proportional to the complexity of the controller. These more complex controllers can be well handled using states machines. Methods to reduce the states in the state machine also help in reducing the required hardware thus leading to low power and area efficient design. The future scope of this project is it can be directly applied in real time by employing more number of such circuits.
